Abstract
The explicit expression for the Green function of the quantum system with the Hamiltonian which is the most general quadratic form of coordinates and momenta with time-dependent coefficients is obtained. The thermodynamical properties of systems with quadratic Haliltonians are briefly discussed.Keywords
